APPARATUS FOR STRAIGHTENING RAILS.

SPECIFIGATIQN forming part of Letters Patent No. 545,283, dated August 27, 1895.

Application filed December 21, 1894. S rial No. 532,529- (No model.)

To all whom it nwty concern.-

Be it known that I, ARCHIBALD M. Gone, a resident of Braddock, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Straightening Rails; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to apparatus for straightening rails, rods, bars, 650., its object being to provide form of apparatus for straightening rails inwhichthe rail is subjected to a pressure at all points along its length at the same time.

My invention comprises, generally stated, the feeding of a rail to a roll having a suitable groove extending lengthwise thereof, bringing a second roll having a corresponding groove therein into position with reference to the groove in said first-mentioned roll as to impart a pressure to the flanges and head of the rail along its entire length, and again bringing a third roll having a corresponding groove therein into coincidence with the groove in said second roll, and again iinparting a pressure to the flanges and head of the rail and discharging the rail straightened therefrom.

To enable others skilied in the art to make and practice my invention 1 will describe the same more fully referring to the accompany ing drawings, in which- Figurel is an end view of my improved apparains; Fig. 2, a plan view; Fig. 3, an enlarged sectional view on the line 3 3, Fig. 2; and Fig. 4t is an enlarged cross-section of the presser used in connection with my invention.

Like letters indicate like parts in each of the figures.

In the drawings, n, represents the housings, which are secured to the bedplate a, by means of the bolts 662. These housings are made sufficient] y massive for the purpose of the invention, and within said housings are supported the brasses b, h, and b Journaled in the brasses Z) are the necks c of the bottom roll 0, and journaled in the brasses b are the necks d of the top roll d, while in front of the said rolls 0 and cl is the roll e, having its neck 6 journaled in the brasses D The bottom roll 0 runs in line with the driving-shaft of the engine and is driven thereby in the ordinary way, and said roll is connected by suitable gearing with the other rolls d and 6, whereby said rolls are driven in the directions indicated by the arrows. The rolls cl and e are adjusted by suitable adjustingscrewsf, passing down through the top of the housings a in the ordinary manner. These rolls 0, (Z, and 6 may be formed of castiron, steel, or wrought-iron, as may be desired. The rolls 0, d, and e are formed with the grooves g g 9 respectively, said grooves extending approximately the entire length of the rolls and of such shape when in conjunction with each other as to form substantially the shape in cross-section of the rail to be straightened. Bearing-blocks hare provided for the rolls 0 and c, said bearing-blocks resting on suitable bed-plates h, secured to the bed-plate by means of the bolts 72?. These bearing-blocks it may be arranged at suitable intervals. Located in front of the roll 6 and at such height as to deliver the rails to said roll is the table 2', said table being supported by'the standards 2" and the beam '6 just above the table t'. Journaled in suitable bearings in the housings are the shafts jj', said shafts having secured thereto at suitable intervals the sprocket-wheels 7o, respectively. The shaft j is connected up with the top roll d by means of the sprocket-chain Z and is accordingly driven thereby. The sprocket-wheels 7t? 7c are connected by the chain 777., the said chain having formed thereon the fingers m m at suitable distance apart.

Mounted on one end of the bottom roll 0 is the bevel-gear u, said gear meshing with the bevel-pinion n on the shaft 0, jonrnaled in' suitable standards 0'. The outer end of the shaft 0 is mounted therein, and the bevelpinion p, which meshes with a bevel-pinion q, mounted on a shaft q, is journaled in suitable standards q This shaft q extends along in the rear of the rolls practically the entire length thereof, and at intervals on said shaft g are the bevel-pinions r, said pinions meshing with the bevel-pinions v" on the shaft 7*, said shafts being journaled in suitable bearings r On the outer ends of the shaft r are the bevel-pinions '1'. On the inner ends of the shafts r are the bevel-pinions s, which mesh with the bevel-pinions s, journaled in suitable standards 8 Mounted on studs t on the pinions s are the cams 6', said cams being adapted to move in contact with the presser it. This presser it extends substantially the entire length of the rolls and is mounted on suitable guides 10, in which it is adapted to slide to and fro. Pitmen "u are connected to the presser u and to the cam for the withdrawal of said presser, as will hereinafterbemorefullyshown. This presser a is composed of the conical member a and the plug member u This plug fits Within the hollow body of the conical member u and is connected thereto by means of the bolts to, which is cast in the said conical member a and passes through a wall to in said plug U13. Nuts :0 so on each side of the wall to provide means for withdrawing said conical member I with the said plug a or advancing said conical member, as may be desired. Openings 1 y are provided in said plug a and the conical member 10?, whereby access may be had to said nuts 0c 00. In the rear of the bottom roll 0 is the discharge-table 2, supported in any suitable way, and at the bottom of said discharge table are the revolving rollers e", driven by suitable mechanism, for the purpose more fully hereinafter set forth.

I will describe the operation of my invention as applied to the straightening of an ordinary railway-rail having the supportingflanges and the head connected by a vertical web. The rail to be straightened is placed upon the table iin such position that fingers m on the chain on will come into contact with said rail and advance it along said table to the rolls. The said fingers m will advance said rail evenly and carry it from the table onto the roll 6 just as the groove 9 in said roll is at such position as to receive one of the flanges and part of the head of said roll. Meanwhile the roll d has revolved until its groove g falls into coincidence with the groove g of the roll 6, whereupon said groove g receives the portion of the roll not taken up by the groove 9 and as both of said rolls continue to revolve they completely inclose the rail along its entire length in said coincident grooves g and g in such manner that a pressure is exerted upon the flanges and head of said rail throughout its entire length. As the rolls (1 and 6 continue to revolve, the grooves g g separate; but in the meantime the bottom roll 0 has revolved until its groove 9 is in position to receive that portion of the rail recently held within the groove 9 of the roll 6, so that said groove g, in conjunction with the groove 9 of the top roll d, again incloses the rail and subjects it to a second pressure. When the rail is thus inclosed by the grooves g and g of the rolls 0 and d, as shown in Fig. 3 of the drawings, the presser u is advanced by means of the mechanism hereinbefore described, so as to press the head of the rail while it is inclosed by the grooves g and g of the rolls a and d. The presser it, however, withdraws immediately upon the further revolution of the rolls 0 and d, so that as said rolls continue to revolve they discharge the rail onto the discharge-plate .2, whence it falls onto the revolving rollers 5', which carry it off.

In the above operation the rail is subjected to a pressure at all points throughout its en tire length at the same time, and a rail is straightened at each revolution of said rolls. It is apparent that the rolls may be adjusted to suit the different sections of the rail, while the conical member M2 of the presser u may also be adjusted to correspond to the height of the rail tobe straightened. I

I do not confine myself to any particular form of rail, as the form of the grooves can be changed to suit difierent forms of rails, rods, bars, and angle-iron.
